Aggregationsschalter

Aggregationsschalter, also known as aggregation switches or distribution switches, are a key component in modern network infrastructure. They are positioned between the access layer (where end-user devices connect) and the core layer (the high-speed backbone of the network). The primary function of an aggregationsschalter is to consolidate traffic from multiple access switches before forwarding it to the core. This hierarchical design helps to manage network complexity, improve performance, and enhance reliability.

By aggregating traffic, these switches reduce the number of connections required to the core network, thereby simplifying the overall topology and reducing costs. They typically support higher bandwidth than access switches, allowing for efficient transmission of aggregated data. Features such as link aggregation (LAG) are commonly found on aggregationsschalter, enabling multiple physical links to be combined into a single logical link for increased throughput and redundancy.

Aggregationsschalter often provide Layer 3 routing capabilities, allowing them to perform inter-VLAN routing and segment the network into smaller broadcast domains. This enhances security and performance by reducing unnecessary broadcast traffic. In larger enterprise networks, they play a crucial role in connecting different departments or floors, acting as a distribution point for network services. Their robust feature set makes them indispensable for efficient and scalable network design.
